Khashoggi won Jill's heart when he wrote a love note on her arm in blood

Speaking on Channel Nine's 60 Minutes on Sunday night, she said: “He pulled up my sleeve and he wrote 'I love you' I was like oh my god that's blood and I was kind of shocked.

“But I thought it was really funny and cute at the same time.”

She eventually agreed to become one of his 11 “pleasure wives” — allowed under Saudi Arabian law — but insists she never thought of herself as a prostitute.

Writing in her memoir, The Currency of Love: A Courageous Journey to Finding the Love Within, Jill revealed: “In that moment, I become a member of Adnan’s harem, taking turns with other women to have sex with the man I love.”

Jill told 60 Minutes’ Peter Stefanovic: “He said, ‘I want to take care of you. I want to make a five-year contract with you’.”

Jill's memoir was published on the same day Kashoggi died - June 6 this year

The model said: “He had this whole compound with several suites ... several different cottages around it.

“I had my own cottage and Adnan’s cottage or Adnan’s house or portion of the compound was private.

“So when I saw him, I would be alone with him in his place or he would come see me in my cottage.”

Lifting the lid on a life of excess, Jill revealed her belief Kashoggi was paying modelling agencies huge sums to get access to gorgeous young women to come to his parties, and have sex with him or his friends.

She said: “We did (cocaine) recreationally. We would lock ourselves in a room for days, we would make love, we would eat, the chef would bring us food.”
